The present invention relates to an apparatus for measuring the sphericity of a ball joint of a tie rod. A pair of guiders into which a tie rod having a ball joint is inserted is formed on an upper portion of a base. A fixing unit which adjusts so that the ball joint is accurately positioned at a measuring position by allowing the outer circumferential surface of the ball joint moved to one side by a moving means to be in contact with two points, and is formed at one side of the upper surface of the base. A measuring means which measures the sphericity of the ball joint by being in point-contact with the ball joint in different angles is installed on an upper portion of the base. Therefore, the apparatus for measuring sphericity of a ball joint of a tie rod can minimize an error range and remarkably reduce test time, thereby increasing productivity. |
